Persist UITableViewCell background color on scrolling tableViewCells - ios

Question

I have a UITableView, when the user taps a cell it turns grey to indicate it is complete. However when the cell is scrolled out of view, when it comes back into view it has returned to its default background colour erasing the users interaction.
Is there a way to persist the cell tapped background color on scrolling?
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as? TodaysRoutineTableViewCell else {
fatalError("Unexpected Index Path")
}
cell.backgroundColor = UIColor.customBackgroundGraphite()
cell.textLabel?.textColor = UIColor.white
configure(cell, at: indexPath)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if let cell = tableView.cellForRow(at: indexPath) {
if cell.backgroundColor == UIColor.customExerciseDoneCellColor() {
cell.backgroundColor = UIColor.customBackgroundGraphite()
} else if cell.backgroundColor == UIColor.customBackgroundGraphite() {
cell.backgroundColor = UIColor.customExerciseDoneCellColor()
}
}
}

The issue is when you scroll after selecting the cell, the selected colour is not retained isn't it??
Cell for row delegate is called whenever you scroll. So even though you set background in Did select delegate its changed when Cell for row is called.
In order to tackle this situation add a boolean to tableview cell and when you select the cell change the boolean status.
In cell for row add this:
if cell.CheckBoolean == true{
cell.backgroundcolor = UI.color()
}else{
cell.backgroungcolor = UI.color()
}
In did select delegate :
change the value of that boolean and reload the table view
